Methane Gas from Sewage Works can now be burnt with the all new Waste Gas Burner supplied by SAUBATECH. The MACROblaze 300W Waste Gas Burner consists of a burner head mounted on a vertical column, which protrudes upwards from a pedestal.

Pilot Gas is fed through a small flame arrestor, a solenoid valve and 15 n/b stainless steel pipe to a toroidal chamber near the top of the column. A ring of replaceable nozzles emit the gas in vertical jets where it mixes with air under the pilot ring before passing upwards and burning in a circle of pilot flames. “The size of the nozzle jets can be changed to suit the size of pilot flame required,” says Peter Thieme of SAFURNCO.

The main gas supply reaches the burner head via the column. A high chrome cast iron turbulator across the top of the column disperses most of the gas sideways and imparts a rotational movement.

Gas enters the column base via a tee piece and passes downwards around the outside of a concentric inner pipe. The inner pipe ends short of the base, allowing the gas to turn inwards and enter the bottom of the inner pipe which forms the column. Flow of the gas is controlled by water in the base of the column. The existence of flame in the burner head is monitored by thermocouple.

A water tank, divided into two compartments, is built into the pedestal. One of the compartments, the water supply tank, is fitted with a ball-cock on the water inlet pipe to keep the water in the supply tank at a constant level.

Water flow from the supply tank to the base of the column is controlled by normally open solenoid valve. When the valve is not energised, water from the tank flows into the column, covers the bottom end of the inner pipe and prevents gas from escaping upwards to the burner head.

The MACROblaze flame trap is designed specifically to absorb the direct blast of an explosion and has build into the inlet side, an automatic shut-off valve which will close when a fusible plus in the outlet of the flame trap reaches an unsafe temperature. These two features are standard equipment and form part of every MACROblaze flame trap.

The standard MACROblaze flame traps have cast iron bodies and stainless steel heat-sinks and auto shut valves. No brass is used in the flame trap thus making it completely suitable for use with sulphur containing gasses such as sewage sludge gas.

For special applications non-standard valves made from other materials such as Aluminium or special stainless steels are available.

All of the flame traps described so far are of the in-line type suitable for gas supply lines to combustion equipment etc. Other flame traps include vent type traps for installation in the vent of large oil and combustible material storage tanks.

Saubatech has always been on the forefront of new products in the insulation industry. For over 25 years they have supplied various sectors in the local and international market with thermal insulation and electric trace heating.

We were the first to manufacture vacuum formed ceramic fibre products locally under license to MH Detrick ( UK ), thereby introducing the country to a extremely light weight refractory material which could be formed into almost any shape from tubes to gaskets.

Ceramic fibre is easily installed with no” drying out” period. Low thermal conductivity, high temperature stability are just some of the advantages of this material. It is also an asbestos free product and can be used for temperatures up to 1800C. Some of the products Saubatech can provide include: blanket, board, felt, mastic, adhesives, coatings, insulating fire bricks, crucibles, Zirconia insulation etc.

Fairly new on the market and due to the pressures of the European Health Organizations, Saubatech can also provide soluble fibres. This product made from amorphous man-made fibres has proven in numerous European tests that the biopersistence of the soluble fibres is very good No significant increase of fibre induced pathology has been observed.

One form of soluble fibre is made from a blend of calcium, silica and magnesium having the ability to support continuous temperatures up to 1100C. They possess excellent insulating properties, are free of binder or lubricant and show good resistance to thermal shock.

Saubatech is manufacturer of a comprehensive range of INDUSTRIAL HEATERS ranging as standard Units from 3kW to 600kW either electric or steam heated.

Custom built OIL PUMPING AND HEATING UNITS which reduce the fuel bill considerable when using heavy oils. These oils need to be heated in order to meet the requirements of existing systems for generating heat or steam.

In addition, electric tank outflow heaters are provided as well as tank heating Units which are supplied as single units or as flanged units incorporating a number of heating elements.

All heating elements are removable and are fitted into extended surface sheaths in order to reduce size and provide the best heat dissipation.

Sanfire sanitary incinerators provide clean, hygienic and safe disposal of sanitary towels and small medical dressings. A Sanfire unit is adequate for up to 40 users and can be connected to a single or common flue system. Opening the charging door automatically switches on the heating element for a pre-set incineration time. Ash residue is simply removed from the lockable drawer.

The robustly-build Sanfire is made of heavy-duty, corrosion-resistant sheet steel and has a stainless steel incineration chamber. For long life and trouble free use, it incorporates a special sheathed wire element, and is easily wall-mounted with the integral keyhole-slotted lugs.

Safe Waste Incinerators are suitable for a number of important applications in industry and the medical sector. Being mobile gives the Safe Waste Unit an important advantage over conventional incinerators because it reduces the need to handle and transport toxic and other dangerous waste because it is incinerated on site.

The Safe Waste Unit is ideal for disposing of medical soft waste as well as a wide variety of industrial and office waste in a cost-effective, environmentally friendly manner. The unit requires no additional fuel for complete incineration.

Needle stick injury, a reality that all medical staff have to worry about because of the dangers of contracting infectious diseases such as Hepatitis, AIDS and many others.

Needle incinerators were especially designed for the safety of all medical personnel at high risk of needle stick injuries, e.g. doctors, nurses, ambulance workers, paramedics and hospital domestic staff or any person who handles hypodermic needles.
